The PS3 scored its biggest sales week ever here in Japan following the release earlier this month of the system's slimline hardware revision. But previous boosts that accompanied releases like Metal Gear Solid 4 and the Advent Children Final Fantasy XIII demo ended up being short-lived.

So how does Sony Computer Entertainment plan on maintaining the system's momentum? We'll hopefully get some insights today as Sony hosts both this year's Tokyo Game Show keynote address followed by its own annual media briefing later in the day.

First, the keynote. Set to be given by CEO Kaz Hirai, the speech is titled "Sony Computer Entertainment 2009 Strategy." TGS keynotes often focus on broad industry issues, but with a name like that, we expect to hear specifics on Sony's year-end game plan.

Hirai's keynote begins at 10:30am local time. Refresh this story around that time for a live blog of the proceedings. Also check the site later in the day (around 1:30pm-ish) for live coverage of Sony's media briefing.
